I will arrive YYZ in January from the United States (CLT) on AC (JAZZ, I believe) and be connecting to AC92 to SCL. Will I have to get my bags, go through immigrations and customs, and then recheck them before going to the gate for my Santiago flight? How much time is needed.

At Vancouver I believe my bags went directly to my international flight (to China) without the need to reclaim, but that I had to go through immigration.

How is this handled in Toronto. What terminal will I fly into and what terminal will I fly out of?
